Metal Silo .—This is also a new type of silo, but should prove 
more successful in warm climates, as the freezing would be exces¬ 
sive even in this temperate climate. The objection made is that 
the acid of silage will attack the metal, but this can be overcome 
by coating' the walls each year, which makes a regular cost of up¬ 
keep. As yet they are rather expensive for farmers to care for 
them much.
